Mexico's President, Claudia Sheinbaum, has sent a letter to Google protesting the tech giant's decision to comply with US President Donald Trump’s order to rename the Gulf of Mexico as the Gulf of America.

During a press briefing on Thursday, Sheinbaum presented the letter to reporters, asserting, “In the case of Mexico, where are we completely sovereign? In the area established as 12 nautical miles from the coastline, and this applies to all countries worldwide.”

She further explained, “If a country wants to change the designation of something in the sea, it would only apply up to 12 nautical miles. It cannot apply to the rest, in this case, the Gulf of Mexico. This is what we explained in detail to Google.”

Sheinbaum also referenced a previous counterproposal she had made to Trump, suggesting renaming the US. She added, “In the end, we requested that when someone searches for ‘América Mexicana’ in the search engine, the map we previously presented should appear.” The map, dating back to 1607, labeled parts of North America as "Mexican America" and was shown during a press conference earlier this month.

On Monday, Google announced that users of Google Maps in the US would see the body of water traditionally known as the Gulf of Mexico renamed as the Gulf of America. The company stated that this change was in line with its “practice of applying name changes when they have been updated in official government sources.”

While users in Mexico will continue to see “Gulf of Mexico” on Google Maps, the rest of the world will be able to view both names.
